Chris Hadfield bids farewall to ISS

Since arriving at the orbital outpost, the space station's first Canadian commander has entertained and enlightened millions with his online messages and videos covering everything from singing in space to explaining how the astronauts brush their teeth. As the 53-year-old's five month mission came to end he bid farewell with a rendition of David Bowie's "Space Oddity" on his trusty guitar.

"We will go to the Moon and we will go to Mars; we will go and see what asteroids and comets are made of," he said in an interview with the BBC. "But we're not going to do it tomorrow and we're not going to do it because it titillates the nerve endings. We're going to do it because it's a natural human progression."

The Soyuz carrying Hadfield and two crewmates touched down successfully earlier today.

"There was danger, hard graft, and the usual antics of life in orbit, but for millions of onlookers the latest mission to the International Space Station was about the rise of a new star: a moustached Canadian with a penchant for guitar."

Wicked .
Last December, astronaut Chris Hadfield aboard the International Space Station, and he's back today with the first music video from space: a cover of David Bowie's "Space Oddity." Hadfield is set to return home to Earth in a Soyuz craft on the morning of May 14th, after a prolific mission in space filled with science, singing, and sharing on Twitter. The video features Hadfield moving throughout the ISS with his guitar, with some impressive vocals to boot — between the setting and the sound, it's a performance that does Bowie justice.

All the people complaining about the cost of this and that not being worth it. If suprising results were found I bet their tune would be different. Yes billions of dollars spent, but if the human race is ever to leave this planet and go elsewhere, money well spent. It's just a shame that billions can't be spent down here to stop starvation and give the homeless a place to live. But of course that would mean the helped people would need to step up and help themselves afterwards. Seeing how messed up the welfare system is, it's easy to see why the billions aren't spent here.

It appeared from the newsreel just after landing, that the astronauts had to sit in chairs. If this is because of muscle atrophy, then what hope of anyone actually going to Mars and landing, then carrying out the myriad of chores that will be necessary?

It has nothing to do with muscle atrophy it has more to do with balance. When Valeriy Polyakov completed his 437 day mission in 1995 he walked immediately he exited the capsule.
Remember that the ISS crew have not experienced normal gravity for 6 months. They are carried to chairs because their is the possibility that they could get dizzy and fall over.
